(a) radius of the base = 30 cm,
height of cylinder = 6 cm
Find the volume :
------------------------
volume of cylinder = πr^2 h
= π × ( 30 )^2 ( 6 ) = π × 900 × 6 =5400π
= 5400 × 22 /7 = 16971.4 cm^3
(b) radius of the base = 14 cm
height of cylinder = 10 cm10
Find the volume :
------------------------
volume of cylinder = πr^2h
= π × (14)^2 × 10 = 1960π
= 1960 × 22/ 7 = 6160 cm^3
